Abstract

A mathematical model of the potentiometric titration of citrate solutions with copper (II) salt that
adequately reflects the influence of ionic strength on the accuracy of determining the equivalence point
built. The way of correction of the analysis results was proposed. The measures to optimize the technique
of titration that reduce systematic error were determined.
